GymPinLeg Extension/Curl Seat Belt Buckle - Achieve Stability and Comfort in Leg Workouts on Machines, 5.6Ft Long

I really love the stability this adds to exercises. It allows you to strap in and focus on the muscle as opposed to holding yourself in place.

Not gym pin, I’ve bought their version. This is a Chinese knife. There is no loose end to tighten quickly. Makes it very difficult to tighten while working out. Do not buy.

Nothing fancy here, works as advertised. Really all I was hoping for.

Easy to adjust, stays in place - does exactly what I need it to. Leg pump is killer on extensions. 5 star!

Doesn’t tighten at all

I just needed something to hold me in the sit with some leg exercises instead of using a lot of energy holding the handles. It works great. But xan kind of dig into me a little.

Can't tighten the belt while you're seated since the buckle itself doesn't lock the belt strap in place. The plastic as the the if the belt is used to lock the belt into place not the buckle so, you've gotta guess where to position it.The buckle itself also isn't great. It's popped open on me a handful of times already in a couple weeks.I wouldn't have purchased it knowing what I know now.

This is a well made seatbelt type device. The quality is great. I only rated it 3 stars because it is very inconvenient to adjust the tightness. I work out with my son and it takes a good minute every time to tighten or loosen the seatbelt for our different sizes. There are so many faster adjusting design methods. If you are only going to set it for one person and rarely need to adjust it, then go for it. If you plan to use it on more than one exercise machine and person like me, its just too inconvenient for me to use.
